Yesterday I committed the last bit of code to support machines with
Sun's UltraSPARC T1 CPUs. Below is a dmesg for the SPARC Enterprise T1000, and although other machines have not been tested yet, machines
like the SPARC Enterprise T2000 and Sun Blade T6300 are expected to
work too. As you can see, we support SMP right from the start.

Whats this European code-slinger extraordinaire now working on?

LDOM support is not yet complete; I'm still working on drivers for
virtual network interfaces and virtual disks. But domains with access
to real hardware should work fine.
